Benefits of technology

This configuration enables efficient one-handed data input and output with high definition display and resolution, reducing the area occupied by signal lines and electric resistance, thus improving operational performance.

Problems solved by technology

For this reason, a keyboard, which requires both hands to be used, a mouse, and the like are not suitable for units for inputting data in a portable information terminal held by a hand.
Further, since a portable information terminal is operated in user's hand, in many cases, the distance between a display portion and user's eyes is short as compared with the cases of a computer, a television set, and the like.
